Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Toyota launches BMW-powered Verso in Europe

BMW makes some sweet-revving engines, but its own vehicles aren't the only ones running BMW engines. So do the latest from Rolls-Royce and Mini, of course, as well as a handful of Peugeots and Citroëns thanks to its joint engine program with PSA. Wiesmann uses BMW engines, as did the famous McLaren F1. And now we can add one more to the list.
That would be the Toyota Verso, a Corolla-based minivan which Toyota builds in Turkey and sells in Europe and a few other markets overseas. The Verso is also now officially the first beneficiary of the partnership between Toyota and BMW as the Japanese automaker has released the MPV with BMW's 1.6-liter turbodiesel four.
The 111-horsepower engine is coupled to a Toyota transmission and joins the Verso range as the fourth (and least powerful) engine in the lineup, alongside the 122hp 2.0 diesel and the gasoline options with 1.6 liters and 160 hp and 1.8 for 180. Future collaborations between the two automakers will include fuel-cell development, a new joint sportscar platform, lightweight bodywork research and a new generation of lithium-air batteries. See the press release below for further details.

BMW crushing ActiveE EVs, saving all batteries

It's unlikely to spark a movement and a movie, the way a certain EV1 did a decade ago, but anyone who's seen Who Killed The Electric Car? will likely cringe at this bit of news. Despite the fact that crushing and recycling old vehicles is standard operating procedure in the auto industry, when EVs are involved, it's always a touchy subject. The next phase will see "all of the lithium-ion batteries being repurposed for Battery Second Life research projects." So, what's the news? Well, the image you see above, which comes from the spotting of 16 smashed BMW ActiveE EVs on flatbed trailers on California Route 91 near Los Angeles, CA. EV advocate Chelsea Sexton told Green Car Reports, "It's all very deja vu, right down to [BMW's] DriveNow promotion as a don't-look-behind-the-curtain distraction – recall GM touting EV1s being donated to museums and universities? – and VINs spray painted on the sides, allowing former drivers to identify their own cars." BMW's take on this is that the ActiveEs were always meant to have a limited lifespan, and their time has come. As spokesman Dave Buchko tells AutoblogGreen, "The learning begun with the ActiveE will transition to the next phase with all of the lithium-ion batteries being repurposed for Battery Second Life research projects." (You can read his full statement below.) Originally, there were 700 ActiveEs leased to Electronauts (give or take). Yahoo! Autos points out that the ActiveEs were originally imported into the US as "pre-production" cars, which means they can't be sold, they can only be used for carsharing projects or re-leased. Eighty of those ActiveEs recently found a second life as vehicles in BMW's DriveNow carsharing fleet in San Francisco (bringing the total of ActiveEs in the program to 150) and "some have also been returned to Munich for additional research markets," Buchko said. The big picture here is that no one should be sad to see these cars go. Yes, they may have had some life left in them, but the rules say their time is done and everything is being done to crush responsibly in accordance with the law. Like Plug In Cars says, we're in a completely different era now than we were when GM crushed all those EV1s a decade ago. Instead of marking the end of a plug-in vehicle program, sending the ActiveEs away to be recycled is a symbol of the evolution and growth of BMW's i Project.
